Bromodifluoromethane
Bromodifluoromethane or Halon 1201 or FC-22B1 is a gaseous trihalomethane or a hydrobromofluorocarbon.
It can be prepared through the reaction of hydrogen and dibromodifluoromethane at temperature in range 400–600 °C.
Critical point data: Tc = 138.83 °C (411.98 K); pc = 5.2 MPa (51.32 bar); Vc = 0.275 dm3·mol−1.
Bromodifluoromethane was used as a refrigerant and in fire extinguishers. It is a class I ozone depleting substance with ozone depletion potential ODP = 0.74, and a greenhouse gas with global warming potential over 100 years of 398, which is nonetheless much smaller than other fluorinated gases due to its relatively short atmospheric lifetime of 5.2 years. It was banned by the Montreal Protocol in 1996.
